南京地区格林-巴利综合征患者的肌电图和运动神经传导速度分析

The Analysis of Electromyography and Motor Nerve Conductive Velocity in Patients with Guillain-Barre Syndrome in Nanjing

目的：探讨肌电图（ＥＭＧ）、运动神经传导速度（ＭＣＶ）及末端潜伏期（ＭＬ）在格林－巴利综合征（ＧＢＳ）中的诊断价值。方法：对南京地区４０例ＧＢＳ患者２２４块肌肉和２０１条神经进行了检测。结果：２０２块肌肉ＥＭＧ异常（９０．２％），１５８条ＭＣＶ减慢（７８．６％），１６８条ＭＬ异常（８３．６％）；ＧＢＳ患者在电生理检测中有很高的异常率，且与病程有密切关系。结论：结合临床作者认为，南京地区ＧＢＳ与北方ＧＢＳ大致相同，以周围神经脱髓鞘为主。

Objective:The purpose of the investigation was to try to explore the value of electromyography (EMG),motor nerve conductive velocity(MCV) and motor nerve latency(ML) in the diagnosis of Guillain-Barre Syndrome(GBS).Method:Two hundred and twenty-four pieces of muscles and 201 pieces of peripheral nerves in 40 cases of GBS were examinated.Rusults:The 90.2% of muscles examined showed abnormal in EMG.The MCV of 78.6% nerves was reduced and ML of 83.6% nerves was prolonged.There was a high percentage of abnormality in electrophysiological test in GBS,which was related to the duration of illness.Conclusion:By conbining the clinical manesfections,we believed that the nature of GBS in Nanjing area was similar to that in northern area in China,characterized by the demyelination of peripheral nerves.The electrophysiological examination was useful for the diagnosis and judging prognosis of GBS.
